TECHNICAL FIELD

The present disclosure relates to a display device that executes aplurality of applications and a method for controlling the displaydevice. More particularly, the present disclosure relates to a displaydevice that controls display of a plurality of windows in which aplurality of applications are executed respectively and a method forcontrolling the display device.

BACKGROUND

A desktop computer is equipped with at least one display device (e.g., amonitor). A mobile device having a touch screen (e.g., a portable phone,a smart phone, or a tablet Personal Computer (PC)) includes one displaydevice.

A user may work at a desktop computer by dividing the screen of adisplay device (e.g., by invoking a plurality of windows throughhorizontal or vertical division of the screen). If a Web browser isexecuted, the user may move upward or downward on a Web page by means ofa page-up button or a page-down button on a keyboard. When the user usesa mouse instead of the keyboard, the user may scroll up or down on theWeb page by selecting a scroll bar at a side of the Web page with amouse cursor. In addition, the user may move to the top of the Web pageby selecting a top button displayed as text or an icon at the bottom ofthe Web page.

Compared to the desktop computer, a mobile device has a small screen andlimitations in input. It is difficult to use the mobile device with thescreen divided into a plurality of areas.

Various applications may be executed in the mobile device, includingbasic applications developed and installed in the mobile device by amanufacturer and additional applications downloaded from applicationsites over the Internet. Ordinary users may develop such additionalapplications and register them to the application sites. Accordingly,anyone may freely sell developed applications on application sites tomobile device users. At present, free or paid tens of thousands tohundreds of thousands of applications are provided to mobile devices.

Although various applications are provided to mobile devices tostimulate customers' interest and meet their demands as described above,the mobile devices have limitations in terms of display size and UserInterfaces (UIs) because the mobile devices are fabricated to portablesizes. As a consequence, mobile device users experience inconvenience inexecuting a plurality of applications. For example, when an applicationis executed in a mobile device, an execution screen of the applicationis displayed in the entirety of a display area on the display of themobile device. If a user of the mobile device wants to execute anotherintended application, the user should first end the ongoing applicationand then select an execution key to execute the intended application.That is, in order to execute a plurality of applications in the mobiledevice, the user should repeat the execution and ending process for eachapplication, which is quite inconvenient. Moreover, no method forexecuting a plurality of applications simultaneously in a mobile devicehas been specified yet.

A plurality of specific applications may be used simultaneously morefrequently than other applications. For example, when a user views avideo lecture, the user is highly likely to use a video play applicationand a memo application at the same time. Accordingly, there is a needfor a technique that enables simultaneous execution of a video playapplication and a memo application. Further, there is a need for atechnique that changes the sizes or positions of a plurality of windowsin which a plurality of applications are executed respectively, asintended by a user.

The above information is presented as background information only toassist with an understanding of the present disclosure. No determinationhas been made, and no assertion is made, as to whether any of the abovemight be applicable as prior art with regard to the present disclosure.

FIG. 2B illustrates the concept of Z-order according to an embodiment ofthe present disclosure.

Referring to FIG. 2B, if the Z-order of a screen is divided into Nlayers, an Nth layer may lie on an (N-1)th layer. A window correspondingto each layer may exist at the layer and an application may be executedin the window. That is, upon execution of a first application, the firstapplication is executed in a first-layer window. Then upon execution ofa second application, the second application is executed in asecond-layer window, and upon execution of a third application, thethird application is executed in a third-layer window. Thus, first,second, and third layers are generated hierarchically. The lastgenerated layer may exist at the top layer and thus may be displayed ontop of the screen. For example, a plurality of windows 1, 2, 3, and 4may be displayed overlapped with one another on the main screen 210.More specifically, the first window 1 is displayed overlapped over thesecond, third, and fourth windows 2, 3, and 4. The second window 2 isdisplayed overlapped over the third and fourth windows 3, and 4, and thethird window 3 is displayed overlapped over the fourth window 4. Whenthe plurality of windows 1, 2, 3, and 4 are overlapped, the ordering ofdisplaying the plurality of windows 1, 2, 3, and 4 is referred to as aZ-order. The Z-order may be the display ordering of windows along a Zaxis. A hierarchical viewer 5 provides a view of hierarchical Z-orders.The Z-order may be referred to as a display order.

FIG. 3A illustrates a screen displaying windows according to anembodiment of the present disclosure. Specifically, FIG. 3A illustratesthe concept of a free style mode.

Referring to FIG. 3A, a display device 300 includes a touch screen 310.A plurality of windows 311 and 312 are displayed on the touch screen310. Further, a bottom bar 320 is displayed at the bottom of the touchscreen 310. As described before, a display mode in which the pluralityof windows 311 and 312 are displayed overlapped with each otheraccording to their display priority levels may be referred to as a freestyle mode.

A window may be defined as an area that covers an execution screen of aspecific application, and a title bar and a control area that areconfigured for the executed application. Objects related to theapplication may be displayed on the execution screen of the application.The objects may have various shapes such as text, a figure, an icon, abutton, a check box, a photo, a video, a Web, a map, and the like. Whena user touches an object, a predetermined function or eventcorresponding to the object may be executed in the application. Theobject may be referred to as a view according to an OS. The title barmay include at least one control key that controls display of thewindow. For example, the at least one control key may include a minimizebutton, a maximize button, and an end button.

Applications are programs configured independently by a manufacturer ofthe display device 300 or an application developer. Therefore, executionof one application does not require pre-execution of anotherapplication. In addition, even though one application ends, anotherapplication may continue.

Compared to an application which is an independently configured program,a composite function application (or a dual application) has a part(e.g., a memory function, a message transmission and reception function,etc.) of the functions of another application in addition to oneapplication (e.g., a video application). Such a composite functionapplication differs from the above independent applications in that itis a single application newly configured to include specific functions.Accordingly, the composite function application provides only limitedfunctions, while various functions are available from existingindependent applications. If a user needs a new composite functionapplication, the user should purchase the composite functionapplication.

The controller 110 controls partially overlapped display of theplurality of windows 311 and 322. The controller 110 may prioritize theplurality of windows 311 and 312 regarding their display. For example,the controller 110 may assign priority to the window 311 over the window312. Thus the controller 110 displays the window 311 with a relativelyhigh priority level over the window 312 with a relatively low prioritylevel. A part of the window 312 hidden by the window 311 is notdisplayed on the screen.

The controller 110 may assign the highest display priority level to awindow for which the latest control event has been input. For example,when the user touches the window 311, the controller 110 assigns thehighest display priority level to the window 311.

FIG. 3B illustrates the concept of a framework according to anembodiment of the present disclosure.

Referring to FIG. 3B, an activity manager 291, a window manager 292, anda view system 294 of a framework 270 may be compatible with amulti-window framework 280. The compatibility with the multi-windowframework 280 may be invoking an Application Program Interface (API) orthe like. The framework 270 may also include a Content Provider 273, aPackage Manager 275, a Telephony Manager 276, a Resource Manager 277, aLocation Manager 278, and a Notification Manager 279.

The multi-window framework 280 includes a multi-window manager 281 and amulti-window service 282.

The activity manager 291, the window manager 292, and the view system294 may invoke a multi-window API. The window manager 292 may generate atitle bar for each window. Further, the window manager 292 may detectthe Z-order of each window and determine the ordering of windows basedon the Z-orders of the windows.

The multi-window manager 281 provides the functionality of themulti-window service 282 in the form of an API to a user and theManager/Service structure may operate based on InterProcessCommunication (IPC).

The multi-window service 282 tracks the life cycles of applicationsexecuted in multiple windows and manages states of each application suchas the size and position of the application.

An invoked API may manage the size, position, and visibility of eachwindow.

As described above, the framework according to the present disclosuremay be operated in a way of providing an independent multi windowframework to invoke the API.

An application layer 260 may invoke an API directly from themulti-window manager 281. That is, when the user develops a newapplication, the user may also use an API provided by the multi-windowmanager 281.

As described above, the multi-window framework 280 may be used and twoor more applications may be displayed simultaneously according to thepresent disclosure.

FIGS. 12A, 12B, 12C, 12D, 12E, 12F, 12G, 12H, 12I, 12J, 12K, 12L, 12M,12N, 12O, 12P, 12Q, and 12R illustrate display devices according tovarious embodiments of the present disclosure.

Referring to FIG. 12A, a display device 1200 displays a menu screen1217. The menu screen 1217 may be an execution screen of a launcherprogram and may include icons with which to execute applications. Themenu screen 1217 may further include information about a current timeand, in addition, may include a widget. Referring to one or more ofFIGS. 12A, 12B, 12C, 12D, 12E, 12F, 12G, 12H, 12I, 12J, 12K, 12L, 12M,12N, 12O, 12P, 12Q, and 12R, the display device 1200 displays a tray1210 at a left side of a touch screen, which contains icons 1211, 1212,1213, and 1214 representing executable applications. The tray 1210 mayfurther contain a shortcut icon edit button 1215 and a shortcut icongeneration button 1216.

As illustrated in FIG. 12B, a user 10 may manipulate the user device1200 to execute a first application A. For example, the user 10 maytouch the icon 1211 representing the first application A and drag thetouch to the menu screen 1217 as illustrated in FIG. 12C. A controller(not shown) of the display device 1200 may control display of the icon1211 at the dragged position. The controller may further control displayof a ghost view 1218 at the dragged position. The ghost view 1218 refersto a preview that displays the size and shape of a window in which anapplication will be executed, so that the user 10 may select theposition of the window. Because no window is displayed, the controllermay display the ghost view 1218 in full screen. As described later indetail, the controller may control full-screen display of a ghost viewin the absence of any window already displayed on the touch screen. If asingle window is already displayed on the touch screen, the controllermay display the ghost view in a size and shape corresponding to a halfof the touch screen. If two windows are already displayed on the touchscreen, the controller may display the ghost view in a size and shapecorresponding to a half of one of the two windows on the touch screen.

The controller may recognize the foregoing drag gesture as a command toexecute a new application. The controller may generate a first window1219 to execute the first application A. The controller may controldisplay of the first window 1219 in full screen as illustrated in FIG.12D.

The user 10 may manipulate the display device 1200 to additionallyexecute a second application B. For example, the user may touch the icon1212 representing the second application B as illustrated in FIG. 12Eand then drag the touched icon 1212 to a lower part of the first window1219 as illustrated in FIG. 12F. The controller may control display ofthe icon 1212 at the dragged position. In addition, the controller maycontrol display of a ghost view 1223 at the dragged position. Asdescribed before, since the single window 1219 is already displayed onthe touch screen, the controller may control display of the ghost view1223 in a size and shape corresponding to a half of the touch screen.While not shown, if the user 10 drags the touched icon 1212 to an upperpart of the touch screen, the controller controls display of the ghostview 1223 in an upper half of the touch screen. Displaying the ghostview in a lower half of the touch screen is purely exemplary. Thus thecontroller may divide the touch screen into left and right halves andmay control display of the ghost view in one of the left and righthalves of the touch screen.

If the user releases the drag in the lower part of the touch screen asillustrated in FIG. 12F, the controller determines that a newapplication execution command has been received. As illustrated in FIG.12G, the controller controls display of a second window 1230 in thelower half of the touch screen in correspondence with the ghost view1223 illustrated in FIG. 12F. Further, the controller shrinks down thefirst window 1219 in size and shape, thus producing a first window 1220so that the first window 1220 may be displayed in the upper half of thetouch screen.

The user 10 may generate a shortcut icon for the first window 1220executed in the upper half of the touch screen and the second window1230 executed in the lower half of the touch screen. For example, theuser 10 may select the shortcut icon generation button 1216 asillustrated in FIG. 12H. Selection of the shortcut icon generationbutton 1216 may be an exemplary command to generate a shortcut icon.Those skilled in the art will readily understand that a shortcut icongeneration command may be issued in a manner other than selection of theshortcut icon generation button 1216.

Upon receipt of the shortcut icon generation command, the controller maycontrol generation and display of a shortcut icon 1235 in the tray 1210as illustrated in FIGS. 12I, 12J, 12K, 12L, 12M, and 12N. Herein, theshortcut icon 1235 may be displayed as an image in which the icon 1211representing the first application is overlapped with the icon 1212representing the second application. Therefore, the user 10 mayrecognize all of the first and second application icon.

Upon receipt of a shortcut icon execution command as the user selectsthe shortcut icon 1235 as illustrated in FIG. 12J, the controller mayexecute and display the first window 1220 in the upper half of the touchscreen and the second window 1230 in the lower half of the touch screen,as illustrated in FIG. 12K.

In another embodiment of the present disclosure, the user 10 may input ashortcut icon edit command by selecting the shortcut icon edit button1215, as illustrated in FIG. 12L. In addition, the user 10 may selectthe shortcut icon 1235 to be edited as illustrated in FIG. 12M. Then thecontroller may display an edit screen 1240 in regards to the shortcuticon 1235 to be edited, as illustrated in FIG. 12N. The edit screen 1240may include a rename tab 1241 that changes the name of the shortcut icon1235 and a remove tab 1242 that deletes the shortcut icon 1235. Uponselection of the rename tab 1241, the controller may control providingof a UI through which the name of the shortcut icon 1235 is to bechanged. Upon selection of the remove tab 1242, the controller maydelete the shortcut icon 1235.

FIG. 12O illustrates a display device according to an embodiment of thepresent disclosure. Referring to FIG. 12O, a controller (not shown) maycontrol display of a screen divided into three parts. For example, thecontroller may control display of a first window 1244 in which the firstapplication A is executed in an upper half of the touch screen, a secondwindow 1242 in which the second application B is executed in a left halfof a lower half of the touch screen, and a third window 1243 in which athird application C is executed in a right half of the lower half of thetouch screen.
